A person must be zealous in his faith in Moshiach's arrival, one of the 13 Principles of our Faith.

It is fitting for one to have a strong desire, a great love and a boundless devotion to the extent that he will say, "Will I be given Redemption in my days?"

Just as one has a desire which is so strong that all his thoughts and longings are totally captivated by this desire, so should one desire the Era of the Redemption in order to reach perfection in body and soul.

With this complete desire, one fulfills the "duty of desiring the salvation."(Shevet Musar, chapter 51)
